Application lgd March 15, 1923.

To all whom it may concern:

Be it known that I, MAURICE M. GLAssEn, a citizen of the United States, and a resident of harleston in the county of Charleston :and State of outh Carolina, have. invented fcentain new and useful Improvements in Fans, of which the following is a full, clear, :and exact description, reference bein had to the accompanying drawings, forming a part of this specilication.

This invention relates particularly to electric ceiling fans although it is applicable to other types of fans as will be apparent from the ensuing description.

In my prior Patent No. 1,354,098, granted September 28, 1920, there is disclosed and .claimed a ceiling fan whose rotor and blades are rotated about a vertical axis and oscillated on a horizontal axis for the purpose of causing the blast of air from the fan blades to move through an arc and changing the direction of that arc. The mechanism in that patent for accomplishing said movements of the rotor and blades, however, requires that the rotation ofthe rotor and blades be dependent on the oscillation of said rotor and blades with the result that if the oscillation ofthe rotor and blades is not constant, the rotation of the rotor and blades will be intermittent.

Therefore, an object of the present invention, stated broadly, is to provide a fan whose rotor and blades are oscillated by suitable mechanism on an axis in one plane to direct the blast of air in an arc and whose rotor and blades are rotated by an entirely independently operable mechanism on a different axis to change the direction of said arc. Whether or not t e rotation of the rotor as well as the oscillation of the same, is constant or intermittent, is immaterial so far as the present invention is concerned for with the two mechanisms arranged independently of each other, either or both of these movements may be constant or intermittent, as desired. Preferably, however, the rotor and blades are moved continuously, as illustrated in the accompanying drawings.

In the drawings-- Fi re 1 is a front view of a fan embodying t e present improvements, portions being` broken away to facilitate illustration;

'g. 2 is a view taken at right angles to Fig. l;

Serial No. 625,348.

Fig. 3 is a detail view o-f the mechanism for securing the independent rotation of the rotor and blades.

`While the present invention is applicable to other types of fans it has, in the present instance, been illustrated as applied to a fan like that disclosed in my prior patent before referred to.

In this type of fan the fan motor proper is enclosed within a casin l0 pivotally mounted on a horizontal axis in a yoke 11 journaled on a vertical stationary hollow post 12 which has a base 13 that may be secured to the ceiling in any desired manner. The lower end of the fan motor shaft 14 carrying the fan blades 15 protrudcs below the casing but it will be understood that this arranwement may be reversed-that is, the blades may be mounted on the casing and said casing rotated, as in some of the well known types of fans. Current is supplied to the fan motor in any suitable way as by conductors 16, 17 connected to brushes 18, 19 which are mounted on a rotating sleeve 20 on post 12 and which contact with rings 21, 22 on said post, said rings being supplied with current by wires 23 leading thereto fr-om a source of supply through the hollow post and through openingp 24 in said post.

or oscillating the casing, motor and blades on the horizontal axis of the casing, the upper end ofthe fan motor shaft 14 extends up into a dome 25 on the casing and is provided at its upper end with a worm 26 which meshes with a worm gear 27 mounted en one end of a horizontal shaft 28 journaled in bearings formed on the casing. The opposite end of the shaft 28 has a disk 29 mounted thereon and said disk is connected by a link 30 to a similar disk 31 mounted on one of the journal pins 32 of the casing. The link 30 is cccentrically connected to each of said disks 29, 31 and upon rotation of said disks by the fan motor shaft the fan motor casing and parts carried thereby will be oscillated on the horizontal axis of said casing, as will be understood. ,A more detailed description of these parts, and of their operation, if found desirable. may be had from my prior patent.

The casing 10, fan motor and blades 15 being supported in yoke 11, the preferred arrangement for rotating the casing, blades, etc., consists in providing means f0.1` I'Olating said yoke on the post l2. lVhile these means ous forkmsfasiar as the present Kinvgfinnior1 in its and its rotor, :1 revolving support for the `rotoaand motor, bladesarmed bythe rotor,
